I have seen too many directories trashed because unexperienced users were playing around with ADSI. To continue this discussion, please ask a new question. Get answers from your peers along with millions of IT pros who visit Spiceworks. Several users have asked questions about this tool With Windows Server , when you view the advanced properties of an object, you will see a new Attribute Editor tab.
You can perform the same tasks here that you can perform in ADSIEdit , but instead of having access to all objects and attributes in your AD DS environment, you are limited to just the object selected. With either version, you can connect to domain controllers and view the Directory Service partitions. Figure From here, you can name the connection you are making to anything that will help you identify the naming context you are accessing.
In the Connection Point text boxes, you can enter the fully qualified name of the naming context to which you are connecting, or you can choose one of the four well-known naming contexts. If you are connecting to one of the new application partitions , identify it by its fully qualified name.
In the Computer section, choose a domain controller to connect to, or default to the domain controller you're logged in to if you are running ADSI Edit from a domain controller. Once you choose the naming contexts and the server to which you are connecting, you see them reflected within the ADSI Edit window, as shown in Figure You can now expand the appropriate naming context to locate the objects you need to manipulate.

For all of the safeguards that Microsoft has provided to ensure that identical security identifiers SIDs are not introduced into a domain, two accounts could still have the same SID if an administrator seizes the Relative Identifier RID Master role while the original RID Master is offline but still operational.
If the original RID Master did not have an opportunity to receive updated replication information and is brought online, it could generate identical RIDs and allow them to be used within the domain. Any time you seize the RID Master role, you should run a check. To check for accounts that may be using identical SIDs, follow these steps:.
Type check duplicate SID and press Enter. The log file that is created from this check is placed within the directory path where you started NTDSUtil. If you are lucky, you will not have any entries within the files. If there are entries, note them and delete the duplicates.
To delete a duplicate SID, follow these steps:. The object with the newer globally unique identifier GUID is removed from the database.
You will then need to re-create the account that was removed during this process.
